摘要
Continued smoking following stroke is associated with adverse outcomes including increased risk of mortality and secondary stroke. The aim of this study was to examine the long-term trends in smoking behaviors and factors associated with smoking relapse among men who survived their first-ever stroke. Data collection for this longitudinal study was conducted at baseline through face-toface interviews and follow-up was completed every 3 months via telephone, beginning in 2010 and continuing through 2014. Cox proportional hazard regression models were used to identify predictors of smoking relapse behavior. At baseline, 372 male patients were recruited into the study. Totally, 155(41.7%) of these patients stopped smoking for stroke, and 61(39.3%) began smoking again within 57 months after discharge with an increasing trend in the number of cigarettes smoked per day. Exposure to environmental tobacco smoke at places outside of home and work(such as bars, restaurants)(HR, 2.34; 95% CI, 1.04–5.29, P=0.04), not having a spouse(HR, 0.12; 95% CI, 0.04–0.36; P=0.0002) and smoking at least 20 cigarettes per day before stroke(HR, 2.42; 95% CI, 1.14–5.14, P=0.02) were predictors of smoking relapse. It was concluded that environmental tobacco smoke is an important determinant of smoking relapse among men who survive their first stroke. Environmental tobacco smoke should be addressed by smoke-free policies in public places.
